Fine fabric that may be watered? (4)
I believe the answer is:
lawn
'fine fabric' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for lawn that I've seen before include "Grassy patch" , "Bowling green" , "Area of short grass" , "Mown grass; cotton" , "Type of thin linen or cotton" .)
